A PROCESS FOR THE MANUFACTURE OF HYDROGEN AND CARBON MONOXIDE SYNTHESIS GAS, WHICH COMPRISES SUBJECTING A C1 TO C4 PARAFFIN HYDROCARBON TO PARTIAL OXIDATION IN THE PRESENCE OF AN OXYGEN CONTAINING GAS AT A TEMPERATURE IN THE RANGE OF 2000 TO 2500* F. AND FOR A PERIOD OF TIME IN THE RANGE OF 0.02 TO 2 SECONDS, RAPIDLY QUENCHING THE PRODUCT OF SAID PARTIAL OXIDATION BY INDIRECT HEAT EXCHANGE WITH A CRACKING STOCK AND THUS RAPIDLY COOLING SAID PRODUCT TO A TEMPERATURE IN THE RANGE OF 1200 TO 1600* F. AND THERMALLY CRACKING SAID CRACKING STOCK, RAPIDLY COOLING THE QUENCHED PARTIAL OXIDATION PRODUCT TO A TEMPERATURE BELOW ABOUT 900* F. TO PREVENT THE FORMATION OF EXCESSIVE CARBON DIOXIDE, SEPARATING THE PRODUCT OF SAID THERMAL CRACKING AND RECOVERING A HYDROGEN AND METHANE FRACTION THEREFROM, A PORTION OF WHICH IS PASSED TO THE PARTIAL OXIDATION REACTION, AND RECOVERING HYDROGEN AND CARBON MONOXIDE FROM SAID PARTIAL OXIDATION IN AN OPTIMUM RATIO IN THE RANGE OF 1.7:1 TO 2.3:1.
